This BA thesis is a meta-analysis that reviews 21 empirical studies on Intimate Partner Violence (IPV) and gender-relations among military families and the environmental structures in where they live and operate. All studies were published between 1978 and 2011 and reported Intimate Partner Violence in both military and civilian families, atrocities committed by both male and female soldiers and causalities on war and violence. My aim is to test the theory that says; war is depending on patriarchal gender-structures, that construct stereotype masculinities and femininities, which define men as strong, aggressive, and unemotional, while women are assumed to be weak, vulnerable, and caring. By examining both positivist and constructivist research, my ambition is to identify differences and similarities in those approaches, which can contribute to a wider understanding on this specific phenomenon.
